Test system dynamic range extension through compression compensation

A method of extending dynamic range of a test system comprising:

• characterizing a reference receiver channel of the test system for a reference magnitude compression response and a reference phase compression response;
• characterizing a second receiver channel of the test system for a second magnitude compression response and a second phase compression response;
• and
• compensating for an effect that compression of one or both of the reference channel and the second channel has on measured magnitude data and measured phase data.

A test system having extended dynamic range comprising:

• a receiver channel;
• a controller that processes magnitude data and phase data generated by the receiver channel;
• and
• a computer program stored in memory, the computer program being executed by the controller, the computer program implementing instructions that compensate for an effect on the generated data caused by the receiver channel being compressed.
